7 WORK ABUTMENT OR STOP FOR WORK-BENCHES.

Application filed April 8, 1915. Serial No. 19,963. 5

following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new and useful work abutment or stop for carpenters benches and the like, and an. object of the invention is to provide asimple and efficient and practical device of this nature,- in which improved features of construction are involved.

In practical fields the details of construc- 7 tion may necessitate alterations, falling Within the scope of what is claimed. i i

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a view in perspective showing the improved stop or abutment as applied to a carpenters work bench, illustrating the abutment partially raised or projecting above the surface of the bench. Fig. 2 is a longitudinal sectional view on line 2-2 of Fig. 1. Fig. 3 is a transverse sectional view on line 33 of Fig. 1. Fig. 4 is a perspective View of the abut- .ment or stop casing detached from the bench.

Fig. 5 is a detail perspective of the abutment removed from its casing.

Referring more especially to the drawing, 1 designates the work bench top havingan opening 2, one of the longitudinal edges of which is alined parallel with the length of the bench while the other edge extends at an angle to the length of the bench. The walls 3 and a of said opening are provided with recesses 5, and 6'denotes a troughshaped casing having one side 7 conforming to the wall 4 of the opening, while the other side 8 conforms to the other angularly extending wall 3 of saidopening. The sides 7 and 8 of the casing 6 are provided with laterally extending flanges 9 and 10'fitting the recesses 5, there being screws 11 to hold said flanges in the recesses. One of the end walls of, the opening 2 is beveled as shown at 12, and the adjacent edges of the end portions 13 of the flanges 9 and 10 curve from each other and terminate short distances Specification of Letters Patent. j

from the end parts of the beveled wall 12 of the opening2, as shown clearly in Figs 1.

- The casing 6 is provided-withan extension casing 141 protruding downwardly, and which is rectangular in cross section. The wall. 15 is. provided with an opening 16 and the side walls 17 of the extension casing 141-. are constructed with recesses 18 adjoining the opening 16,- and these recesses 18' form bearings for the shaft pin19, which is provided with a pinion 20, a hand wheel 21 and two collars 22 and 23. The collar 22 engages one of the side walls 17 a of the extension casing, and interposed between the collar 22 .and the collar 23 isea coil spring 25, thereby holding the pinion 2Ov adjacent the inner face 26 of one of the sides 17 of the extension casing. This spring not only holds the pinion against the inner face, but also in engagement with alug 27 thereby preventing the shaft pin from being rotated, until the shaft pin is pulled in the direction of the arrow (0 against the action of said spring. When the shaft pin is pulled in such direction it is free to be rotated, and by its rotation the pinion imparts vertical movement to the rack bar 27, which is guided by and mounted in the extension casing 14. The collar 23 is held upon the extremity of the shaft pin by the cotter key 28.

Forming an integral part of the upper end of'the rack bar is a trough-shaped work abutment or stop 29, the side 30 of which is in parallelism with and fits against the side 31 of the casing 6, whereas the side 32 of the stop or abutment is angularly disposed with relation to the bench and fits against the angularly disposed side of the casing 6. Each of the sides 30 and 32 adj acent one end is provided with a laterally extending flange v33 having a curved edge 34L fitting the curvature of each of the flanges 9 and 10. The rear portions of the flanges 33are provided with teeth 35, which are en gaged by the edge of a flat board or the like when planing or dressing the same. The rear parts of the sides 30 and 32 are curved or beveled downwardly or forwardly to correspond with and fit the wall 12 of the opening 2. Theabutment or stop is constructed trough-shaped with one of its sides angularly disposed, so that a board or the like,

when disposed upon one of its longitudinal edges, may be received therein, the angularly extending wall 32 preventing forward movement of the board.

Then it is desired to move the rack vertically, so as to adjust the stop or abutment to the proper position above the surface of the work bench, the shaft pin is pulled outwardly in the direction of the arrow a, against the action of the spring, thereby disengaging the pinion from the lug on the inner face of one of the sides 17 of the extension casing, after which a partial revoluble or rotary movement is imparted to the shaft pin, which also imparts movement to the pinion, which in turn raises and lowers the rack bar to the requisite position.

The opening 16 allows the pinions to pass into the extension casing when inserting the shaft pin.

The invention having been set forth, what is claimed as new and useful is In combination with a work bench having an opening, a casing trough-shaped in cross sion casing, the lower portion of the extension casing having recesses in its opposite side forming bearings, the rear wall of the extension casing having an opening adjoining said recesses, a shaft pin mounted in said bearings and provided with a pinion meshing with the rack bar to impart a vertical movement thereto when the shaft pin is 1'0- tated, the opening in the extension casing constituting means through which the pinion may be passed so that the shaft may be inserted through the pinion, a lug on the inner face of one of the sides of the exteir sion casing to be engaged by the pinion to prevent its rotation, and a spring on the shaft pin and against the action of which the shaft pin may be shifted to disengage the pinion from the lug, whereby the rack and its second trough-shaped casing may be adjusted vertically.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
